First releace | Carve Audio - Gas Can Amp

Published: 03.06.2026

The original “The Can” amplifier was a small, battery-powered amplifier from the 1980s. Carve Audio has now released it as a plugin.

Since the original guitar amplifier is not only a rarity these days but also an obscure piece of music history, it’s worth taking a closer look at it first.

The amplifier was produced in the mid-1980s by SLM Electronics. SLM (St. Louis Music) was a major U.S. instrument distributor that also owned the Crate and, later, Ampeg brands. "The Can" was manufactured in the same factory in St. Louis (USA) as the early Crate amplifiers.


Construction and Design of the Original

  • Enclosure: The most striking feature is the enclosure, which consists of a blue plastic canister modeled after a gas can. 
  • Technology: It was a small, battery-powered solid-state amplifier (transistor) that was actually designed as a portable solution for street musicians (buskers). 
  • Speaker: It featured a small 5-inch speaker. 
  • Operation: The circuitry was kept extremely simple. The amp was basically known for one setting: all controls set to maximum. It offered hardly any options for sound shaping other than volume and a simple gain control.


The Sound and the Legend of the Original

The sound of “The Can” is described as extremely gritty, buzzing, and aggressive. The combination of the small speaker, the cheap electronics, and the resonant plastic enclosure produced a very distinctive, lo-fi distortion that is difficult to achieve with standard amplifiers.

The amp gained its greatest fame through the recordings for the first Foo Fighters album (1995).  Producer Barrett Jones and Dave Grohl used the amplifier for several guitar tracks (including songs like “Exhausted” and “Weenie Beenie”) to create the raw, dirty grunge sound.  Since only a few units were manufactured (estimates put the number at around 10,000) and they were long considered worthless, the original is now a sought-after collector’s item that fetches high prices on the secondhand market. 


The plugin for the legend

Of course, the plugin aims to stay as true to the original as possible—that’s the whole point. 

On the Carve Audio website, you can read this quote from Barret Jones: 

"I LOVE IT! It actually does sound very close to the real thing, and I think you’ve done a great job with the look and controls."

Gas Can Amp is available for macOS and Windows in VST3, AU, and AAX formats. The price is $49. You can try it out for 14 days with the free trial. An iLok is not required.
